The seller has the corresponding obligation to fulfill the transaction i. An option that conveys to the owner the right to buy at a specific price is referred to as a call ; an option that conveys the right of the owner to sell at a specific price is referred to as a put. The seller may grant an option to a buyer options theory part of another transaction, such as a share issue or as part of an employee incentive scheme, otherwise a buyer would pay a premium to the seller for the option.

The theory has become a popular theme in most business schools across the world, as well options theory the boardroom, especially within oil companies.

In other words, the project is like an option: there options theory an opportunity, but not an obligation, to go ahead with it. The expected cash flows are discounted at the capital cost for the company, and the results are added up. If the NPV is zero, it makes no difference to the company whether the project is approved or turned down.
Option pricing theory uses variables stock price, exercise price, volatility, interest rate, time to expiration to theoretically value an option. Essentially, it provides an estimation of an option's fair value which traders incorporate into their strategies to maximize profits. Some commonly used models to value options are Black-Scholesbinomial option pricingand Monte-Carlo simulation. Understanding Option Pricing Theory The primary goal of option pricing theory is to calculate the probability that an option will be exercised, or be in-the-money ITMat expiration. Underlying asset price stock priceexercise pricevolatilityinterest rateand time to expiration, which is the number of days between the calculation date and the option's exercise date, are commonly used variables that are input into mathematical models to derive options theory option's theoretical fair value.
If it is greater than zero, NPV theory tells us to go ahead with the project. The higher the managerial freedom degree, the higher is the value of the investment opportunity.
For most capital investment in petroleum industry, the timing is the main option to be considered. In many cases, for large sunk cost like investment in offshore petroleum fields, is possible to consider only the timing option.

In petroleum exploration contract auctions, it is common for the largest bids to be greater than the net present value calculation. This is because the winning bidder was aware that as soon as some initial drilling was completed, the company could — on the basis of the new information gathered from that initial digging — stop the exploration or expand it.
As occurs with financial options, the key question is when to exercise that option: certainly not when the company has no funds the cost of investing is greater than the benefit. Investors in financial options should options theory necessarily invest as soon as they have money, when the benefit of making that choice is greater than the cost — a better option may be to wait until it has lots of money, when the benefits are considerably greater than the cost.
Similarly, firms should not always invest as soon as their project has an NPV equal to or marginally greater than zero — waiting might be better.
Introduction to Options Theoretical Pricing Option pricing is based on the unknown future outcome for the underlying asset. If we knew where the market would be at expiration, we could perfectly price every option today. No one knows where the price will be, but we can draw some conclusions using pricing models. When looking at call options, a higher strike will cost less than options theory lower strike. If the underlying asset price has risen dramatically and you chose a higher strike price rather than a lower strike, your payoff will be less because you have foregone the first part of the upward price movement.
When the cost of investing is much less than the benefit Real options theory allows you to wait until you are here before deciding to approve the project Real options theory — an example The majority of companies have embedded in them investment opportunities with a range of managerial options.
For example, imagine an oil company whose management thinks it has discovered a new oil field.

However, nobody knows exactly how much oil is in there — neither do they know what the oil price will be when they start pumping that oil. They have two decisions to make: — Purchase the lease and start drilling?
We know that oil prices can fluctuate significantly.
So, it would make more sense to wait until oil prices were considerably higher than an NPV equation of slightly more than or equal to zero before giving the go-ahead. In practice, however, valuing real options is extremely difficult, as are pricing the financial options. Video — What are real options? It starts by comparing them to financial options.
